Oops, a build error.
Somehow my experimental and not working cygwin.c slipped into the src packa=
ge.
Please try the official cygwin/cygwin.c from
http://github.com/rurban/perl/raw/49c38585884a547ae094a6be3f8a37db3018e48d/=
cygwin/cygwin.c
until I roll an update.

Slaven Rezic is very cooperative and also has cygwin.
